Application filed June 27, 1907.

To all whom 'it may concern:

Be it known that we, EDMUND H. LUN- KEN and CHARLES M. CONKLIN, citizens of the United States, residing at Cincinnati, Ohio, have invented certain new and useful Improve-ments in Fireproof l/Vindow Construction, of which the followingis a specification.

Our said invention relates to fire-proof window construction and is designed as an improvement, in respect to certain features or details upon the construction which forms the subject of an application filed 'by us in the United States Patent Office on the 22nd day of November, 1906, Serial No. 344,643. i

We have aimed, in devising the present inventicn, to provide a framehaving very desirable means for guiding the weights, and having also finishing or facing plates designed to give a more complete and finished appearance to the frame. We have also incorporated with the frame corner blocks whichy not only fill' in the spaces left at the corners between the side and the top and bottom lfinishing plates,vbut also carry blind and shade-and curtain supporting devices. l/Ve also add a brass weather-strip yto one` of the inwardly projecting flanges of the outer frame which bears against the side of Vthe cover plate when in place.

With these and other objects in view the invention includes the various features of construction and Varrangement and combinar tion of parts hereinafter described and' articularly ointed out in the appended claims.

An emli in the accompanying drawings, in which,-

Figure l is a perspeetiveview. Fig. 2 is an enlarged front elevation showing the upper and lower corners and with the central part broken away. Fig. 3 is a section on line 3-'3 of Fig. 1'. Fig. 4 is a perspective view of one of the lower corner blocks. Fig. 5 is a central vertical section of one of the blind counter-balancing weights. Fig. 6, is a perspective view of one ofthe upper corner blockswith the parts carried thereby. Figs. 7 and 8 are detail views showing respectively the` fastenings for the upper andA lower ends of the guide rods or Wires. Fig. 9 is a section of the flange 5 of Fig. 3 showing brass weather strip. Fig. 10' is a vertical section of the upper and lower corners on the lines 3a-3aofFig. 1. y

ous figures, the numeral 2 designates the top cross member or piece, 3 the bottom member or sill, and 4-4 the sides. The top and sill may be constructed substantially as illustrated and ldescribed in our aforesaid applica- 6@ tion. -The sides we provide with integral ribs or flanges 5 formed by pressing or folding the material of which the frame is constructed. These ribs form guides for the masons in walling in the frame. We also provide a Weather strip 4 on the outer .edge of flange 5 which forms a weather-tight joint between the outer frame and the coverplate. The open sides of the frame are designed to be closed by removable coverplates in the manner de- 7@ scribed in our previous application, but in the present form, the cover-plates `for the side members of the frame which are designated by the numeral 6, are provided with Aoutwardly turned flanges or sides as shown at 7, 8, which are preferably formed of an ogee curve in cross section and bear at their outer edges against the outer edges of the webs or flanges 5, and thus completely cover the frame members which are not given the high 8@ finish which is imparted to the coverplates. The sides or flanges 7, 8 thus form ornamental moldings and are braced by the A flanges 5, and prevented from being dented or pressed in. Each side frame member is g5 also preferably provided withan integral flange or rib 9 formed by pressing or folding thematerial of which the frame member is constructed, as clearly shown in Fig. 3, this flange forming a wind break. Each side 90 member is provided withweight guides which may be conveniently formed of two pieces of sheet metal having webs 10 riveted together and angularly turned portions lOariveted orl otherw1se secured to the outer wall of the side 95 member. Each member has both edges turned over to-form webs' or flanges 10b and 10'c against which the weights 11 abut, the weights being preferablyof rectangular form rlhe sash cord is attached in such a manner that the weightsare caused to bear only on the edges of these flanges so that all the friction and wear is at thesel points and there is no friction or wear against the walls of the weight boX.

It will be apparent that unless the meeting corners of the side and top and bottom plates are made of special construction, a square space will be left uncovered by the coverp ates. 'We provide a filling for this space 110 at'each corner in the shape of a block properly designed to match the molding of the coverplates, and which is also utilized for the support or attachment of a shutter blind or the'like, and also preferably atthe to p has means for sup )orting a shade roller and a curn tain pole.

screws 18 shown in Figs. 4, 6 and 10 screwed into lace from the inside of the side frame mem ers before the coverplates are'applied.

The top blocks 12 on the inside of the frame are preferably provided with outwardly projecting arms 14. Each of the top blocks on the inside of the frame has a vertical opening in a projecting portion or lug, as indicated at 15, which is. countersunk and which receives a nipple v15a to which is secured one end of guide rod or wire 16. The lower end of the guide rod 16 is connected to a hook or eye bolt 17, `which passes throu h a similar opening in a lug on the lower lock and is held. therein by a milled nut 18 by which tension may be placed on the wire. The arm 14 carries a pulley 19 over whichpasses a cord 20, one end of which is secured to the upper end of a slat shutter 21, while the other end is .attached to the weight22-- The weight .22 is provided on each side for counterbalancing the weight of the slat shutter and is prefer ably made hollow so that it may be filled with shot or other heavy material to secure the desired weight, and has an interior tube 21a through which the guide rod 16 passes and guides the weight in its vertical movement.

'The shutter-frame is guided by4 arms or brackets whose ends slide in the grooves 6 in the side coverplates 6. Arms'14 are provided with recesses 23 of a shape suitable for receiving the ends of the ordinary shaderoller, while the extreme outer ends of the arms are providedfwith seats for the receptionof the ordinary curtain pole.

The weather strip 4 shown in Fig. 9 is preferably made of thin spring brass strips, which are folded over the edge of the outer vflangep and extend up the sides and across the top of the outer frame.

Having thus described our invention, what we claim is 1. In fire-proof window construction, a

frame member having guide iianges on opposite sides thereof, portions projecting in advance of the guide flanges, and removable 'finishing plates embracing said projecting portions and having molded edges abutting against said flanges.

-2. In'fire proof window construction,'a
